Profile: Drillstar Industries specializes in providing tubing, casing, drilling, and milling services. We manufacture standard and premium threads (box and pin). The whole range of casing and tubing accessories include cross-over, pup joints, flanges, plugs, nipples, and locators. We can provide a full range of cross-overs and subs, with sizes up to 20 inches outer diameter. Our drilling cross-overs & subs are made using non-magnetic steel, inconel, monel, stainless steel, aluminum, and titanium. 3-point or 6-point roller reamers (also know as rotary reamers) are designed for reaming and stabilization in any type of formation. All parts of the tools are made of special alloy steel, and heat treated for hardness. Drilling screws can easily replace any part in the field without the use of special tools. Reamers are available in a wide range of standard and custom sizes, up to hole size 26".
